201026786 六、發明說明: 【發明所屬之技術領域】 本發明係關於一種聚鹵化鋅酞青素顏料組成物,可得 到對比度的耐熱性優異的彩色濾光片;一種含有此聚鹵化 鋅酞青素顏料組成物而成之感光性組成物;及,一種彩色濾 光片’於綠色像素部含有此聚鹵化鋅酞青素顏料組成物且 即使於高溫長時間進行液晶顯示亦可得到對比度降低小的 影像。 @ 【先前技術】 聚鹵化金屬酞青素顔料,已知有如C_I.顏料綠36的聚 鹵化銅酞青素顏料,以及其以外的聚鹵化異種金屬酞青素 顏料。其中,如C.I.顏料綠58之聚鹵化鋅酞青素顏料,係 如聚鹵化鋁酞青素二聚物(dimer)顔料,顯示其他的聚鹵化 異種金屬酞青素顏料所沒有的特殊性質。 具體而言’已知將此聚鹵化鋅酞青素顏料應用於液晶 顯示裝置之彩色濾光片之綠色像素部。含有此聚鹵化鋅酞 G 青素顏料之綠色像素部,Tmax相較於含有習知之聚鹵化銅 酞青素顏料的綠色像素部,位於高波長側,故色純度較高, 即使與黃色顏料混色的情形,綠色區域的透光量亦多,適 於應用在高色純度彩色濾光片(專利文獻1)。 即便是此優異的聚鹵化鋅酞青素顏料,由於彩度不足 且色再現區域尙無法令人滿意,因此以往係藉由在聚鹵化 鋅酞青素顏料中使用含有甜菜鹼型兩性界面活性劑形成的 顏料組成物,以確保更爲優異的彩度及更廣的色再現區 201026786 域,並於液晶顯示裝置之影像顯示中達到更爲接近理想的 RGB色再現性(專利文獻2)。 [專利文獻1]日本特開2003-1 6 1 827號公報 [專利文獻2]日本特開2007-284592號公報 【發明內容】 (發明欲解決之問題) 然而,彩色濾光片製備所使用的如C.I.顏料綠36、C.I. 顏料綠58的聚鹵化金屬酞青素顔料,比起以往的油墨或塗 Ο 料所使用者更爲微細,因此,使用其所得到的彩色濾光片, 還是未解決以下問題;當液晶顯示裝置受到於高溫的熱履 歷時,影像顯示的對比度下降。 本發明欲解決的問題在於提供一種聚鹵化金屬酞青素 顏料組成物,其即使受到於高溫的熱履歷也不會有色相變 化,適於形成耐熱性優異之彩色濾光片的綠色像素部。 又,本發明欲解決的問題在於提供前述顏料組成物的 較佳製造方法,及提供彩色濾光片,此彩色濾光片於綠色 ® 像素部含有前述顏料組成物,即使於高溫進行長時間的影 像顯示,對比度的降低亦小。 (解決問題的方式) 本案發明人等,對於使各種表面處理劑含於聚鹵化金 屬酞青素顏料後給予熱履歷時的色相變化進行評價,發現 到;藉由使用聚胺基甲酸酯樹脂,當製成彩色濾光片時可 得到對比度的耐熱性優異的聚鹵化金屬酞青素顏料組成 物’於綠色像素部含有如此種聚鹵化金屬酞青素顔料組成 201026786 物而構成的彩色濾光片即使於高溫長時間進行影像顯示, 與以往相比,對比度降低仍較小,乃完成本發明。 亦即’本發明提供彩色濾光片用顏料組成物,特徵爲; 曰有C.I.顏料綠58及/或C.I.顏料綠36(A),及聚胺基甲酸 酯樹脂(B),且以質量基準計,CI.顔料綠58及/或c.I.顏 料綠36(A)每1〇〇份,聚胺基甲酸酯樹脂(B)非揮發成分爲 0 . 1〜1 0份。 又,本發明提供彩色濾光片用顏料組成物之製造方 參法’特徵爲,混合C.I.顏料綠58及/或C.I.顏料綠36(A), 與聚胺基甲酸酯樹脂水性分散體,使以非揮發成分的質量 基準計’ C.I.顏料綠58及/或C.I.顏料綠36(A)每ι〇〇份, 聚胺脂樹脂(B)爲〇.1~1〇份,之後,將液體介質去除。 又’本發明提供彩色濾光片,係使上述彩色濾光片用 顔料組成物或以上述製造方法得到之彩色濾光片用顏料組 成物含於綠色像素部而成。 (發明之效果) Θ 本發明之聚鹵化金屬酞青素顏料組成物,由於含有聚 胺基甲酸酯樹脂,故即使受到於高溫的熱履歷也不會有色 相變化,可發揮耐熱性優異的格外顯著的效果。 本發明之含有聚鹵化金屬酞青素顏料組成物的彩色濾 光片,比起含有習知的聚鹵化金屬酞青素顏料組成物的彩 色濾光片’即使於高溫長時間進行影像顯示,比起以往可 發揮對比度降低較小的格外顯著的效果。 【實施方式】 201026786 (實施發明的最佳形態) 以下詳細說明本發明。以下有時將C.I.顏料綠58及/ 或C.1·顏料綠36(A)簡稱爲顏料(A)或前者顏料(A)。同樣 @ ’ Μ胺基甲酸酯樹脂(B)有時簡稱爲樹脂(B)或後者樹脂 (Β)。 本發明中,彩色濾光片用顏料組成物,特徵爲;含有 C.I.顏料綠58及/或C.I.顏料綠36(A),及聚胺脂樹脂(Β), 以質量基準計,前者顏料(幻每100份,後者樹脂(Β)爲 β 0.1〜10 份。 本案發明人等,利用嘗試錯誤,於顏料(Α)中使包含種 S的界面活性劑或聚合物而比較對比彩色濾光片用感光性 組成物的耐熱性,發現到;僅是少量含有聚胺基甲酸酯樹 脂(Β)得到的顏料組成物製作成彩色濾光片時,即使特地在 高溫長時間使用,色相變化亦少,且對比度降低小,耐熱 性優異。 本發明中,顔料(Α),爲係聚鹵化鋅酞青素顏料的C.I. ® 顏料綠58、係聚鹵化酮酞青素顏料的C.I.顏料綠36,及此 等的混合物。以下,將聚鹵化鋅酞青素顔料及聚鹵化銅酞 青素顏料一倂稱爲聚鹵化金屬酞青素顏料。 本發明中,顏料(Α),以初級粒子的平均粒徑爲 0·01~0.30μηι的聚鹵化金屬酞青素顏料爲佳。 又’本發明中,初級粒子的平均粒徑係以穿透型電子 顯微鏡JEM-201 〇(日本電子股份有限公司製)拍攝視野內的 粒子’且對於二維影像上的構成凝集體的顏料(A)或本發明 201026786 的顏料組成物的50個初級粒子,各求其較長的直徑(長徑) 並且平均後之値。此時,爲樣品的顔料(A)或本發明的顏料 組成物’係以超音波使分散於溶劑後以顯微鏡拍照。又, 也可使用掃描式電子顯微鏡來取代使用穿透型電子顯微 鏡。 聚溴化鋅酞青素顏料,例如C · I.顏料綠5 8,例如,DIC 股份有限公司製FASTOGEN(註冊商標)GREEN KTY-CF、同 FASTOGEN(註冊商標)GREEN A -11 〇等。聚溴化銅酞青素 ® 顏料,例如c.l.顏料綠36,例如;Die股份有限公司製 FASTOGEN(註冊商標)GREEN 2YK-50、同 FASTOGEN(註冊 商標)GREEN 2YK-53、同 FASΤΟGEN(註冊商標)GREEN 2YK-CF 等。 其中,C.I·顏料綠58,比起C.I.顏料綠36,當製作爲 彩色濾光片時,爲高色純度,於能達成更高水準的輝度及 更理想的RGB色再現性的觀點爲較佳。 本發明宜將初級粒子的平均粒徑爲0.01〜Ο.ΙΟμιη的聚 ® 溴化鋅酞青素顏料使用於彩色濾光片用途。 本發明中,聚胺基甲酸酯樹脂(Β),係以1分子中含有 2個胺酯鍵結爲必要。此聚胺基甲酸酯樹脂(Β)中,也包含 不僅是胺酯鍵結,更含有脲鍵結的聚胺基甲酸酯聚脲樹脂 等。 聚胺基甲酸酯樹脂(Β),例如;聚醚系聚胺基甲酸酯樹 脂、聚醚酯系聚胺基甲酸酯樹脂、聚酯系聚胺基甲酸酯樹 脂等,但是,聚酯系聚胺基甲酸酯樹脂由製作爲後述彩色 201026786 濾光片時的耐熱性優異之觀點爲較佳。 聚胺基甲酸酯樹脂(B),爲僅使有機二異氰酸酯及二元 醇及視需要的二官能鏈伸長劑反應成的線狀熱可塑性聚胺 基甲酸酯樹脂者,由其皮膜特性優異、容易操作的觀點亦 爲較佳。 聚胺基甲酸酯樹脂(B)於後述感光性組成物製備時使 用的黏結劑樹脂或單體爲(甲基)丙烯酸酯樹脂或(甲基)丙 烯酸酯時,由可發揮優異的分散安定性的觀點爲佳,主鏈 Φ 包含含有芳香環的直鏈芳香族單位及陰離子性基之聚胺基 甲酸酯樹脂在密合性、耐久性這些皮膜特性方面優異之觀 點,爲較佳。其中,於主鏈包含含有芳香環之直鏈芳香族 單位及陰離子性基之使用脂肪族或脂環式二異氰酸酯得到 之聚酯系聚胺基甲酸酯樹脂,耐熱性更爲優異,由長時間 進行液晶顯示時影像的對比度降低小的觀點尤佳。又,在 此,陰離子性基指例如羧基、磺酸基等酸基或將此等酸基 以鹼中和獲得之鹽。此優異的耐熱性係藉由於後詳述的耐 ® 熱性試驗而首次得知者,係從常態觀察不進行耐熱性試驗 所無法徹底得知的。 此尤佳的聚胺基甲酸酯樹脂,例如;.使用前述含有直 鏈芳香族聚酯單位之於主鏈包含含有芳香環之直鏈芳香族 單位及陰離子性基,且使用脂肪族二異氰酸酯或脂環式二 異氰酸酯作爲有機二異氰酸酯而獲得的聚胺基甲酸酯樹 脂。如後述,形成彩色濾光片之像素部時使用的顏料,比 起直接使用(無處理)時的輝度,一般而言進行某些表面處 201026786 理的情形輝度會變小,但是當以上述尤佳的聚胺基甲酸酯 樹脂處理C.I.顏料綠58時,反而有輝度比起未處理的情形 提高的特殊性。 可將聚胺基甲酸酯樹脂(B)的非揮發成分直接與前述 顏料(A)混合而製成本發明的顏料組成物,也可將顏料 (A) ,與將樹脂(B)溶解或分散於液體介質得到之溶液或分 散液混合之後’將液體介質除去,藉此製備爲顏料(A)與樹 脂(B)更爲均勻混合的顏料組成物。此混合宜於攪拌下進 ® 行。其中’將顏料(A)與將樹脂(B)溶解或分散於液體介質 而成的溶液或分散液混合攪拌並進行加熱,比起不進行加 熱的情形能更爲均勻且確實的將樹脂(B)被覆在顔料(A)的 表面。又,藉由加壓加熱,不僅是單只是於加熱時將樹脂 (B) 被覆於顏料(A)粒子的表面,還能促進樹脂(B)滲透到顏 料(A)粒子的細孔狀空隙部分,使被覆的效果更爲提高。 此時,液體介質若使用僅使用水或以水作爲主體而含 有水溶性有機溶劑之液體介質(稱爲水性介質),則比起液 ® 體介質僅使用有機溶劑而進行前述混合加熱的情形,顔料 (A)本身的結晶形狀等的變化少,色相變化亦少,故爲較佳。 使聚胺基甲酸酯樹脂(B)分散於水性介質而獲得的分 散體,稱爲聚胺基甲酸酯樹脂水性分散體。 本發明中使用的聚胺基甲酸酯樹脂’例如;Hydran(註 冊商標)AP-40F、同AP-30F、同AP-20(以上,DIC股份有 限公司製)、Superflex460、同460S、同126(以上’第一工 業製藥股份有限公司製)等聚胺基甲酸酯樹脂水性分散體。 -10- 201026786 本發明中,混合顏料(A)與樹脂(B)水性分散體,使以 非揮發成分的質量基準計,前者顏料(人)每j 00份,後者樹 脂(B)成爲0.1〜1〇份’其中較佳爲〇.5〜5份,尤佳爲1〜3 份後’將液體介質去除,製造顏料組成物爲佳。以此方式 加入的後者樹脂(B)即使進行後述處理也不會流出,以質量 基準計其非揮發成分的至少70 %留在顏料(A)中。 顏料(A)與樹脂(B)之加熱,可將兩者混合後,於密閉 系於溫度100〜150 °c攪拌下,進行30分鐘〜5小時的範圍。 © 藉由如此於密閉系加熱,形成加壓狀態,如前述,聚胺基 甲酸酯樹脂(B)滲透直到顏料粒子的空隙,比起單只被覆粒 子表面,可展現更爲優異的效果。 如此進行加熱的混合物,可藉由例如冷卻,並由此除 去液體介質,並視需要將固體物質進行清洗、過濾、乾燥、 粉碎,得到含有顏料(A)與聚胺基甲酸酯樹脂(B)之本發明 之顏料組成物的粉體。 清洗可採用水洗、熱水洗任一者。清洗次數,也可在 ® 1~5次的範圍內重複進行。藉由清洗,可輕易地將未吸附 於顏料(A)的樹脂(B)去除。若有需要,也可利用不使結晶 狀態變化的方式,進行酸清洗、鹼清洗、溶劑清洗。含於 彩色濾光片用顏料組成物中的爲有效成分的樹脂(B)非揮 發成分的量(所謂的產量),可由例如顏料組成物的溶劑萃 取而得的樹脂萃取量’或相對於加入樹脂(B)的濾液中的流 出量求得。 上述分濾、清洗後的乾燥,例如,可利用設置在乾燥 -11- 201026786 機的加熱源進行80~120°C的加熱,將顏料脫水及/或脫溶劑 的批式或連續式乾燥等,乾燥機一般而言有箱型乾燥機、 傳送帶乾燥機、噴霧乾燥機等。尤其,噴霧乾燥於糊體製 作時容易分散,故爲較佳。又,乾燥後的粉碎,並非使比 表面積增大或使初級粒子的平均粒徑減小的操作,係於使 用箱型乾燥機、傳送帶乾燥機乾燥時當顏料變成渣滓狀時 用於將顏料解碎並粉末化而進行,例如利用硏缽硏磨、錘 磨、磐磨、針磨、噴射硏磨等之粉碎等。如此可得到以含 ® 有含顏料(A)及樹脂(B)的彩色濾光片用顏料組成物作爲 主成分的乾燥粉末。 本發明之彩色瀘光片用顏料組成物可用於公知慣用的 任一用途,尤其若初級粒子的平均粒徑爲0.01〜0.10 μιη,則 顏料凝集也較弱,對於待著色的合成樹脂等的分散性會更 爲良好。 本發明之彩色濾光片用顏料組成物,當使用於彩色濾 光片綠色像素部時,容易對於彩色濾光片用感光性組成物 ® 進行顏料分散,於將彩色濾光片用感光性組成物硬化時常 用的365nm的遮光性下降,且光阻的光硬化感度不會降 低’顯影時不易發生膜厚減薄或圖案流動,故爲較佳。可 更爲簡便地得到近年來要求的鮮明度及明度均高的彩色濾 光片綠色像素部。 本發明之彩色濾光片用顏料組成物的初級粒子,若進 一步的縱橫比(aspectratio)爲1~3,則於各用途領域的黏度 特性提升,流動性更高。爲求出縱橫比,首先,與求取初 -12- 201026786 級粒子的平均粒徑的情形同樣,以穿透式電子顯微鏡或掃 描式電子顯微鏡拍攝視野內的粒子。並且,就二維影像上 的構成凝集體的50個初級粒子求出較長直徑(長徑)、較短 直徑(短徑)的平均値,並使用此等値計算而得。 藉由使本發明之彩色濾光片用顏料組成物至少含於彩 色濾光片的綠色像素部,可得到本發明的彩色濾光片。於 彩色濾光片領域中,與以往的印刷油墨或塗料這種泛用用 途不同,彩度値的處理非常嚴密,就算彩度値僅極些微提 〇 升也有其困難,但是藉由將本發明的顏料組成物使用於彩 色濾光片的製備,可得到色純度更提高且RGB色再現區域 更廣的液體顯示裝置。 含有C.I·顔料綠58之本發明的理想彩色濾光片用顏料 組成物,於獲得彩色濾光片之綠色像素部時,不必爲了調 色而特別倂用黃色顏料,或即使倂用也僅需少量即足,故 可將於3 8 0〜78〇nm全域的光穿透率的降低抑制在最小限 度。尤其’具有更泛黃且更高著色力,故若爲同等色濃度, ® 可倂用更少量的黃色顏料,可使穿透率更爲提高而爲有利。 又’含有C.I.顔料綠58的本發明的理想彩色濾光片用 顏料組成物’如前所述,於3 80〜780nm的分光穿透光譜的 穿透率成爲最大時的波長(了^“爲51〇〜52〇nm,其穿透曲 線的半値寬爲UOnm以下,非常陡峭。(此波長不受如後述 感光性樹脂的影響)。 本發明中’分光穿透光譜係依據日本工業規格ns Z 8722顏色測定方法-反射及穿透物體顏色)的第一種分光測 -13- .201026786 光器求得者,係對於玻璃基板等之上製膜爲前述既定乾燥 膜厚的含有顏料組成物的樹脂被覆膜掃描照射既定波長區 域的光,並將各波長的各穿透率値加以繪圖而成。彩色濾 光片的穿透率,可藉由對於以僅由樹脂製成相同乾燥膜厚 的被覆膜以同樣方式求得的分光穿透光譜校正(基線校 正),以更佳精度求得。 本發明之彩色濾光片用顏料組成物,可直接用於製造 彩色濾光片的綠色像素部,但若有需要,也可考慮經濟性 ® 而倂用公知慣用的綠色或黃色的顏料或顏料衍生物。 又’綠色顏料以外,爲使展現特色,有時會使用黃色 顏料調色。在此可倂用的黃色顏料,例如C.I.顏料黃83、 同110、同138、同139、同150、同180、同185等黃色 有機顏料。 本發明之彩色濾光片用顏料組成物,可以利用公知的 方法用於形成彩色濾光片的綠色像素部的圖案。典型而 言’可得到含有本發明之彩色濾光片用顏料組成物及感光 ® 性樹脂作爲必要成分的彩色濾光片綠色像素部用感光性組 成物。 彩色濾光片的製造方法,例如稱爲光微影的方法,將 此彩色濾光片用顏料組成物分散於由感光性樹脂構成的分 散介質後,以旋塗法、輥塗法、噴墨法等塗布在玻璃等透 明基板上,接著隔著光罩以紫外線對於此塗布膜進行圖案 曝光後,以溶劑等清洗未曝光部分而得到綠色圖案。 此外,也可使用電著法、轉印法、膠束電解法、PVED(光 -14- 201026786 伏電沉積(Photovoltaic Electrodeposition))法的方法形成 綠色像素部的圖案,並製造彩色濾光片。又,紅色像素部 的圖案及藍色像素部的圖案也可使用公知的顏料以同樣方 法形成。本發明的彩色濾光片用顏料組成物由於即使受到 熱履歷的色相變化亦小,故於例如步驟包含烘烤的彩色濾 光片的製造方法極爲有用。 爲了製備彩色濾光片綠色像素部用感光性組成物,例 如將本發明之彩色濾光片用顏料組成物、感光性樹脂、光 φ 聚合起始劑,及溶解前述樹脂的有機溶劑作爲必要成分混 合。其製造方法,一般係將本發明之彩色濾光片用顏料組 成物及有機溶劑及視需要使用分散劑製備成分散液後,於 其中加入感光性樹脂等並製備。 視需要使用的分散劑,例如Big chemie公司的 disperbyK(disPerbyK 爲註冊商標)130、disperbyK 161、 disperbyK 162' disperbyK 163 、disperbyK 170、Efka 公 司的Efka4 6、Efka47等。又,也可倂用勻塗劑、偶合劑、 ® 陽離子系的界面活性劑等。 有機溶劑,例如甲苯或二甲苯、甲氧基苯等芳香族系 溶劑、乙酸乙酯或乙酸丁酯、丙二醇單甲醚乙酸酯、丙二 醇單乙醚乙酸醋等乙酸酯系溶劑、乙氧基乙基丙酸酯等丙 酸醋系溶劑、甲醇、乙醇等醇系溶劑、丁基賽珞蘇、丙二 醇單甲醚、二乙二醇乙醚、二乙二醇二甲醚等醚系溶劑、 甲乙酮、甲基異丁酮、環己酮等酮系溶劑、己烷等脂肪族

000質量份的有機溶劑,及視需要的〇~ 100質量份 的分散劑及/或〇~20質量份的酞青素衍生物攪拌分散使成 Θ 均勻狀可得到分散液。接著,於此分散液中,本發明之彩 色濾光片用顏料組成物每1質量份添加3〜20質量份的感光 性樹脂,感光性樹脂每1質量份添加〇.〇5〜3質量份的光聚 合起始劑,及視需要更添加有機溶劑,並攪拌分散成均勻 狀,可得到彩色濾光片綠色像素部用感光性組成物。 此時可使用的感光性樹脂,例如;胺甲酸酯系樹脂、 丙烯酸系樹脂、聚醢胺酸系樹脂、聚醯亞胺系樹脂、苯乙 烯馬來酸系樹脂、苯乙烯馬來酸酐系樹脂等熱可塑性樹 ® 脂,或例如;二丙烯酸1,6-己二醇酯、二丙烯酸乙二醇酯、 二丙烯酸新戊二醇酯、二丙烯酸三乙二醇酯、雙(丙烯醯氧 乙氧基)雙酚A、二丙烯酸3-甲基戊二醇酯等2官能單體、 三羥甲基丙烷三丙烯酸酯、三丙烯酸季戊四醇酯、參(2-羥 基乙基)異氰酸酯、六丙烯酸二季戊四醇酯、五丙烯酸二季 戊四醇酯等多官能單體等光聚合性單體。 光聚合起始劑,例如;苯乙酮、二苯基酮、苄基二甲 基縮酮、過氧化苯甲醯基、2-氯噻噸酮、1,3-雙(4’-疊氮亞 -16 - 201026786 苄基)-2-丙烷、1,3-雙(4’-疊氮亞苄基)-2-丙烷-2’-磺酸、 4,4’-二疊氮莲-2,2’-二磺酸等。 將如此所製備的彩色濾光片綠色像素部用感光性組成 物,隔著光罩以紫外線進行圖案曝光後,將未曝光部分以 有機溶劑或鹼水等清洗,可成爲彩色濾光片。 本發明之彩色濾光片用顔料組成物,爲更泛黃的綠色 且著色力高,會以高色純度發出高對比度的明亮的綠色。 因此,除了詳記的彩色濾光片用以外,也適用於塗料、塑 φ 料、印刷油墨、橡膠、雷射、印染、電子給予者、噴墨、 熱轉印油墨等的著色。 其次具體說明本發明的實施例。以下若無特別指明,

Pigment Green 36, and a polyhalogenated dissimilar metal ruthenium pigment other than the above are known. Among them, a polybromide zinc anthraquinone pigment such as C.I. Pigment Green 58 is a polyhalogenated anthocyanin dimer pigment which exhibits special properties not found in other polyhalogenated dissimilar metallocene pigments. Specifically, it is known that the polybromide zinc ruthenium pigment is applied to a green pixel portion of a color filter of a liquid crystal display device. The green pixel portion containing the poly-zinc-zinc phthalocyanine pigment has a Tmax which is higher on the high-wavelength side than the green pixel portion containing the conventional polyhalogenated copper phthalocyanine pigment, so that the color purity is high even if it is mixed with the yellow pigment. In the case where the green region has a large amount of light transmission, it is suitable for use in a high color purity color filter (Patent Document 1). Even this excellent polyhalide zinc anthraquinone pigment has been used in the poly-zinc-containing phthalocyanine pigment to contain a betaine-type amphoteric surfactant because the chroma is insufficient and the color reproduction region is unsatisfactory. The pigment composition is formed to ensure a more excellent chroma and a wider color reproduction area 201026786, and achieve a more ideal RGB color reproducibility in the image display of the liquid crystal display device (Patent Document 2). [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. 2007-284592 (Patent Document 2) Japanese Laid-Open Patent Publication No. 2007-284592 (Draft of the Invention) However, the color filter is used for the preparation of the color filter. For example, CI Pigment Green 36 and CI Pigment Green 58 polyhalogenated metal phthalocyanine pigments are finer than those of conventional inks or coating materials. Therefore, the color filters obtained using them are still unresolved. The following problem: When the liquid crystal display device is subjected to a high temperature heat history, the contrast of the image display is lowered. The problem to be solved by the present invention is to provide a polyhalogenated metal phthalocyanine pigment composition which is suitable for forming a green pixel portion of a color filter excellent in heat resistance even if it is subjected to a hue change without being subjected to a heat history at a high temperature. Further, the problem to be solved by the present invention is to provide a preferred method for producing the pigment composition, and to provide a color filter containing the pigment composition in a green color pixel portion, even at a high temperature for a long period of time. The image shows that the contrast reduction is also small. (Attachment of the problem) The inventors of the present invention evaluated the hue change when various surface treatment agents were contained in the polyhalogenated metallocallin pigment and then gave a heat history, and found that by using a polyurethane resin When a color filter is produced, a polyhalogenated metal phthalocyanine pigment composition excellent in contrast heat resistance can be obtained, and a color filter composed of such a polyhalogenated metal phthalocyanine pigment composition 201026786 is contained in a green pixel portion. Even if the image is displayed at a high temperature for a long period of time, the contrast reduction is small as compared with the prior art, and the present invention has been completed. That is, the present invention provides a pigment composition for a color filter characterized by; CI pigment green 58 and/or CI pigment green 36 (A), and polyurethane resin (B), and 1〜1 0份。 The benchmark, CI. Pigment Green 58 and / or cI Pigment Green 36 (A) per 1 part, the polyurethane resin (B) non-volatile components are 0. 1~1 0 parts. Further, the present invention provides a method for producing a pigment composition for a color filter, characterized by mixing CI Pigment Green 58 and/or CI Pigment Green 36 (A) with an aqueous dispersion of a polyurethane resin, On the basis of the mass of the non-volatile component, 'CI Pigment Green 58 and/or CI Pigment Green 36 (A) per mp part, the polyurethane resin (B) is 〇.1 to 1 part, and then the liquid Media removal. Further, the present invention provides a color filter comprising a pigment composition for a color filter or a pigment composition for a color filter obtained by the above-described production method, which is contained in a green pixel portion. (Effects of the Invention) The polyhalogenated metal ruthenium pigment pigment composition of the present invention contains a polyurethane resin, so that it does not change in hue even when subjected to a heat history at a high temperature, and exhibits excellent heat resistance. Extraordinarily significant effect. The color filter containing the polyhalogenated metallocyanine pigment composition of the present invention exhibits image display even at a high temperature for a long time compared to a color filter containing a conventional polyhalogenated metallocene pigment composition. In the past, it has been shown to have an exceptionally significant effect of reducing the contrast. [Embodiment] 201026786 (Best Mode for Carrying Out the Invention) The present invention will be described in detail below. Hereinafter, C.I. Pigment Green 58 and/or C.1. Pigment Green 36 (A) may be simply referred to as Pigment (A) or Pigment (A). Also, the @' urethane resin (B) is sometimes simply referred to as the resin (B) or the latter resin (Β). In the present invention, the pigment composition for a color filter is characterized by containing CI Pigment Green 58 and/or CI Pigment Green 36 (A), and a polyurethane resin (Β), based on the mass basis, the former pigment (illusion) The resin (Β) is 0.1 to 10 parts per part per 100 parts. The inventors of the present invention used the surfactant or polymer containing the species S in the pigment (Α) to compare the color filter with a trial error. The heat resistance of the photosensitive composition was found; when a pigment composition obtained by containing only a small amount of a polyurethane resin was used as a color filter, even if it was used at a high temperature for a long period of time, the hue change was small. In the present invention, the pigment (Α) is a CI ® pigment green 58 which is a polybromide zinc ruthenium pigment, and a CI pigment green 36 which is a polyhalogenated ketone anthraquinone pigment, and Hereinafter, the polybromide zinc ruthenium pigment and the polyhalogenated copper ruthenium pigment are collectively referred to as a polyhalogenated metal ruthenium pigment. In the present invention, the pigment (Α) is an average particle diameter of the primary particles. Polyhalogenated gold of 0·01~0.30μηι Further, in the present invention, the average particle diameter of the primary particles is a particle image in the field of view by a transmission electron microscope JEM-201 (manufactured by JEOL Ltd.) and on a two-dimensional image. The pigment (A) constituting the aggregate or the 50 primary particles of the pigment composition of the present invention 201026786, each having a longer diameter (long diameter) and an average after enthalpy. At this time, the pigment of the sample (A) Or the pigment composition of the present invention is photographed by a microscope after being dispersed in a solvent by ultrasonic waves. Alternatively, a scanning electron microscope may be used instead of using a transmission electron microscope. Polyzinc bromide anthraquinone pigment, for example, C · I. Pigment Green 5 8, for example, FASTOGEN (registered trademark) GREEN KTY-CF manufactured by DIC Co., Ltd., FASTOGEN (registered trademark) GREEN A -11 〇, etc. Polybromide copper phthalocyanine pigment, such as cl Pigment Green 36, for example, FASTOGEN (registered trademark) GREEN 2YK-50 manufactured by Die Co., Ltd., FASTOGEN (registered trademark) GREEN 2YK-53, FASΤΟGEN (registered trademark) GREEN 2YK-CF, etc. Among them, CI·Pigment 58, compared with CI Pigment Green 36, when producing a color filter, it is preferable to have a high color purity, and it is preferable to achieve a higher level of luminance and more desirable RGB color reproducibility. The poly® zinc bromide anthraquinone pigment having an average particle diameter of 0.01 to Ο.ΙΟμηη is used for a color filter. In the present invention, the polyurethane resin (Β) is contained in one molecule. It is necessary to bond two amine esters, and the polyurethane resin (Β) also contains a polyurethane urethane resin which is not only an amine ester bond but also a urea bond. a polyurethane resin, for example, a polyether-based polyurethane resin, a polyether ester-based polyurethane resin, a polyester-based polyurethane resin, etc. The polyester-based polyurethane resin is preferable from the viewpoint of excellent heat resistance when it is produced as a color 201026786 filter to be described later. The polyurethane resin (B) is a linear thermoplastic polyurethane resin obtained by reacting only an organic diisocyanate and a diol and optionally a difunctional chain extender. Excellent and easy to operate views are also preferred. The polyurethane resin (B) exhibits excellent dispersion stability when the binder resin or monomer used in the preparation of the photosensitive composition described later is a (meth) acrylate resin or a (meth) acrylate. It is preferable that the main chain Φ contains a linear aromatic unit containing an aromatic ring and an anionic group of the polyurethane resin, and is excellent in terms of film properties such as adhesion and durability. Among them, a polyester-based polyurethane resin obtained by using an aliphatic or alicyclic diisocyanate containing a linear aromatic unit and an anionic group of an aromatic ring in the main chain is more excellent in heat resistance and long in length. It is particularly preferable to reduce the contrast of the image when the time is displayed on the liquid crystal display. Here, the anionic group refers to an acid group such as a carboxyl group or a sulfonic acid group or a salt obtained by neutralizing these acid groups with a base. This excellent heat resistance was first known from the heat resistance test described later in detail, and it was not completely known from the normal state that the heat resistance test was not performed. Particularly preferred polyurethane resin, for example, uses the above-mentioned linear aromatic polyester unit in the main chain to contain a linear aromatic unit and an anionic group containing an aromatic ring, and an aliphatic diisocyanate is used. Or a urethane resin obtained as an organic diisocyanate as an alicyclic diisocyanate. As will be described later, the pigment used in forming the pixel portion of the color filter is generally smaller than the luminance at the time of direct use (no treatment), and in some cases, the brightness of the surface is reduced at the time of 201026786, but when When a good polyurethane resin is used to treat CI Pigment Green 58, the brightness is more specific than that of the untreated one. The non-volatile component of the polyurethane resin (B) may be directly mixed with the pigment (A) to form the pigment composition of the present invention, or the pigment (A) and the resin (B) may be dissolved or dispersed. After the solution or dispersion obtained in the liquid medium is mixed, the liquid medium is removed, whereby a pigment composition in which the pigment (A) and the resin (B) are more uniformly mixed is prepared. This blend is suitable for mixing under the ® line. In the case where the pigment (A) and the solution or dispersion in which the resin (B) is dissolved or dispersed in a liquid medium are mixed and stirred and heated, the resin can be more uniformly and surely obtained without heating. ) is coated on the surface of the pigment (A). Further, by pressure heating, not only the resin (B) is coated on the surface of the pigment (A) particles but also the resin (B) is infiltrated into the pore-like void portion of the pigment (A) particles. To make the effect of the coating more effective. In this case, when a liquid medium containing a water-soluble organic solvent (referred to as an aqueous medium) using only water or water as a main component is used as the liquid medium, the above-described mixed heating is performed using only the organic solvent as the liquid medium. The pigment (A) itself preferably has a small change in the crystal shape or the like and has a small change in hue. The dispersion obtained by dispersing the polyurethane resin (B) in an aqueous medium is called an aqueous dispersion of a polyurethane resin. The polyurethane resin used in the present invention is, for example, Hydran (registered trademark) AP-40F, the same AP-30F, the same AP-20 (above, manufactured by DIC Corporation), Superflex 460, the same 460S, the same 126 An aqueous dispersion of a polyurethane resin such as the above (manufactured by First Industrial Pharmaceutical Co., Ltd.). -10-201026786 In the present invention, the aqueous pigment (A) and the aqueous dispersion of the resin (B) are mixed so that the former pigment (human) is used for every 00 parts, and the latter resin (B) is 0.1% based on the mass of the nonvolatile component. It is preferable to prepare a pigment composition by removing the liquid medium from 1 part of which is preferably 〇5 to 5 parts, particularly preferably 1 to 3 parts. The latter resin (B) added in this manner does not flow out even after the treatment described later, and at least 70% of the nonvolatile matter thereof remains in the pigment (A) on a mass basis. The pigment (A) and the resin (B) are heated, and after mixing the two, they are allowed to stand in a sealed state at a temperature of 100 to 150 ° C for a period of 30 minutes to 5 hours. © By heating in a sealed system, a pressurized state is formed. As described above, the polyurethane resin (B) penetrates into the voids of the pigment particles, and exhibits a more excellent effect than the surface of the single coated particles. The mixture thus heated can be removed by, for example, cooling, and thereby removing the liquid medium, and if necessary, washing, filtering, drying, and pulverizing the solid substance to obtain a pigment (A) and a polyurethane resin (B). A powder of the pigment composition of the present invention. Washing can be washed with water or hot water. The number of cleanings can also be repeated in the range of 1-5 to 5 times. The resin (B) not adsorbed to the pigment (A) can be easily removed by washing. If necessary, acid cleaning, alkali cleaning, and solvent cleaning can be performed by changing the crystal state. The amount of the non-volatile component (so-called yield) of the resin (B) as an active ingredient contained in the pigment composition for a color filter, the amount of resin extracted by solvent extraction of, for example, a pigment composition' or relative to The outflow amount in the filtrate of the resin (B) was determined. The above-mentioned filtration and drying after washing can be carried out, for example, by heating at 80 to 120 ° C using a heating source provided in a dry -11-201026786 machine, and drying or desolvating the pigment in batch or continuous drying. The dryer generally has a box dryer, a conveyor dryer, a spray dryer, and the like. In particular, spray drying is preferred because it is easily dispersed during the paste system. Further, the pulverization after drying is not an operation for increasing the specific surface area or reducing the average particle diameter of the primary particles, and is used for decomposing the pigment when the pigment becomes slag-like when dried using a box dryer or a conveyor dryer. It is crushed and powdered, for example, pulverization by hammering, hammering, honing, needle grinding, jet honing, or the like. Thus, a dry powder containing a pigment composition for a color filter containing a pigment (A) and a resin (B) as a main component can be obtained. The pigment composition for a color light-receiving sheet of the present invention can be used for any of the conventionally known applications. In particular, if the average particle diameter of the primary particles is 0.01 to 0.10 μm, the pigment aggregation is also weak, and the dispersion of the synthetic resin to be colored or the like is dispersed. Sex will be better. When the pigment composition for a color filter of the present invention is used in a green pixel portion of a color filter, it is easy to perform pigment dispersion on the photosensitive composition for a color filter, and to use a photosensitive composition for a color filter. When the object is hardened, the light-shielding property at 365 nm is lowered, and the light-hardness sensitivity of the photoresist is not lowered. It is preferable that film thickness reduction or pattern flow is unlikely to occur during development. It is possible to more easily obtain a color filter green pixel portion having a sharpness and a high brightness which have been required in recent years. When the primary particle of the pigment composition for a color filter of the present invention has a further aspect ratio of 1 to 3, the viscosity characteristics in each application field are improved and the fluidity is higher. In order to obtain the aspect ratio, first, the particles in the field of view were imaged by a transmission electron microscope or a scanning electron microscope in the same manner as in the case of obtaining the average particle diameter of the particles of the primary -12-201026786. Further, the average enthalpy of the long diameter (long diameter) and the shorter diameter (short diameter) is obtained for the 50 primary particles constituting the aggregate on the two-dimensional image, and is calculated by using the enthalpy. The color filter of the present invention can be obtained by including the pigment composition for a color filter of the present invention at least in the green pixel portion of the color filter. In the field of color filters, unlike the general use of conventional printing inks or coatings, the processing of chroma 値 is very strict, and even if the chroma 値 is only slightly increased, it is difficult, but by the present invention The pigment composition is used for the preparation of a color filter, and a liquid display device having improved color purity and a wider RGB color reproduction region can be obtained. When the pigment composition for an ideal color filter of the present invention containing CI·Pigment Green 58 is used, when the green pixel portion of the color filter is obtained, it is not necessary to use a yellow pigment for the coloring, or even if it is used, A small amount is sufficient, so the reduction of light transmittance in the entire range of 380 to 78 〇 nm can be suppressed to a minimum. In particular, it has a more yellowish and higher tinting strength, so if it is of the same color density, ® can use a smaller amount of yellow pigment to make the penetration rate more favorable. Further, as described above, the pigment composition for an ideal color filter of the present invention containing CI Pigment Green 58 has a wavelength at which the transmittance of the spectral transmittance spectrum at 380 to 780 nm becomes maximum (" 51〇~52〇nm, the half-turn width of the breakthrough curve is UOnm or less, which is very steep. (This wavelength is not affected by the photosensitive resin as described later.) In the present invention, the 'spray light transmission spectrum is based on the Japanese industrial specification ns Z The first type of spectrophotometry of the 8722 color measurement method - reflection and penetration of the object color -13.201026786 The photoreceptor is a resin containing a pigment composition which is formed on the glass substrate or the like to have the predetermined dry film thickness. The coating film scans the light of a predetermined wavelength region and draws the respective transmittances of the respective wavelengths. The transmittance of the color filter can be made by using the same dry film thickness made of only the resin. The coating film is obtained in the same manner as the spectral penetration spectrum correction (baseline correction), and is obtained with better precision. The pigment composition for a color filter of the present invention can be directly used to manufacture green pixels of a color filter. Ministry, but If necessary, you can also consider the economical ® and use the well-known green or yellow pigments or pigment derivatives. In addition to the 'green pigments, in order to show the characteristics, sometimes use yellow pigment tones. The yellow pigment, for example, CI Pigment Yellow 83, the same 110, the same 138, the same 139, the same 150, the same 180, the same 185 and the like yellow organic pigment. The pigment composition for a color filter of the present invention can be used by a known method. The pattern of the green pixel portion forming the color filter. Typically, the photosensitive color of the green pixel portion of the color filter containing the pigment composition for a color filter of the present invention and the photosensitive resin as an essential component can be obtained. A method for producing a color filter, for example, a method called photolithography, wherein the color filter pigment composition is dispersed in a dispersion medium made of a photosensitive resin, and then spin coating or roll coating is used. An inkjet method or the like is applied onto a transparent substrate such as glass, and then the coating film is subjected to pattern exposure with ultraviolet rays through a mask, and then the unexposed portion is washed with a solvent or the like to obtain a green pattern. In addition, the pattern of the green pixel portion can be formed by using an electrophoresis method, a transfer method, a micelle electrolysis method, a PVED method, and a color filter can be manufactured by using a method of PVED (Photo-14-201026786 Photovoltaic Electrodeposition). Further, the pattern of the red pixel portion and the pattern of the blue pixel portion can be formed in the same manner using a known pigment. The pigment composition for a color filter of the present invention is small even if it undergoes a hue change in the heat history. For example, the method for producing a color filter containing baking is extremely useful. In order to prepare a photosensitive composition for a green pixel portion of a color filter, for example, a pigment composition for a color filter of the present invention, a photosensitive resin, and light are used. The φ polymerization initiator and the organic solvent in which the above resin is dissolved are mixed as essential components.
